Cushion cut diamonds buying guide

A cushion cut diamond is a hybrid of a square and a round shape, often referred to as a “pillow cut” due to its soft, rounded edges. This cut is known for its vintage appeal, dating back to the 19th century, and remains popular due to its timeless elegance. Unlike other shapes, the cushion cut has a unique facet pattern that enhances the diamond’s brilliance, making it a favorite for engagement rings and fine jewelry.

There are two main variations of the cushion cut stone: the cushion brilliant cut and the cushion modified brilliant cut. The cushion brilliant cut features larger facets, which result in broader flashes of light, while the cushion modified brilliant cut includes additional facets, creating a “crushed ice” appearance. This distinction is critical when selecting a cushion cut diamond, as the choice between the two can significantly affect the diamond’s overall look and brilliance.

Standard vs. modified cushion cut diamonds

When discussing types of cushion cut diamonds, it’s essential to understand the difference between the standard and modified cuts. The standard cushion cut is closer to the original 19th-century design, with 58 facets arranged in a unique pattern that maximizes the stone’s natural fire and brilliance. This cut often appeals to those seeking a classic, vintage look.

On the other hand, the cushion modified brilliant cut adds extra facets, typically along the pavilion, which gives the diamond a more modern sparkle. This cut can create a “crushed ice” effect, where the light dispersion is more scattered, offering a different type of brilliance compared to the broad flashes seen in a standard cushion cut.

Cushion cut vs. other shapes

The cushion cut diamond is often compared with other popular shapes like the round, radiant, and oval cuts. For instance, the cushion cut versus round debate often centers on brilliance. While round cuts are known for their unparalleled sparkle, cushion cuts offer a unique blend of brilliance and vintage charm. The larger facets of a cushion cut can emphasize clarity and color more than a round cut, making it essential to choose a higher clarity and color grade when opting for a cushion cut.

Similarly, when comparing the radiant cut diamond vs cushion, it’s essential to note that the radiant cut is more rectangular with cropped corners, offering a more modern look. The radiant cut tends to hide inclusions better due to its facet pattern, whereas the cushion cut’s larger facets can make inclusions more visible. This is why clarity becomes a significant consideration for cushion cuts.

What are the pros and cons of cushion cut diamonds?

Like all diamond cuts, the cushion cut diamond comes with its advantages and disadvantages. One of the primary benefits is its versatility in design. The cushion cut works well in various settings, from solitaire to halo, and its soft edges complement both modern and vintage styles.

However, the cushion cut is not without its drawbacks. Due to its larger facets, a cushion cut can highlight inclusions and color tints more than other cuts, such as the round or radiant. This means that when shopping for cushion diamonds for sale, it’s crucial to prioritize higher clarity and color grades. Additionally, while the cushion cut is generally less expensive than the round cut, it may still be more costly than other shapes like the oval or princess cut due to its popularity.

When selecting a cushion diamond cut, the quality of the cut is paramount to ensuring the diamond’s beauty and brilliance. The ideal length-to-width ratio for a cushion cut ranges from 1.00 to 1.05 for a square appearance and 1.10 to 1.20 for a rectangular look. The girdle diamond definition—the thin perimeter of the diamond—is another critical factor. A well-proportioned girdle is essential to prevent chipping and to ensure the diamond reflects light optimally.

The depth percentage and table size also play significant roles in the diamond’s overall appearance. For cushion cuts, a depth percentage between 61% and 68% is ideal, as it helps to maximize brilliance without making the diamond look too deep or shallow. The table size should range from 58% to 64%, balancing the diamond’s sparkle with its structural integrity.

What is the best color rating to choose for a cushion diamond ring?

Color is a significant factor when selecting a cushion cut diamond. Due to the larger facets, cushion cuts can show color more than some other shapes. For a cushion diamond shape, a color grade of H or above is typically recommended to ensure a near-colorless appearance, especially when set in white gold or platinum.

However, if you’re interested in a more vintage or warmer look, a lower color grade (I or J) might be preferable, especially in a yellow gold setting. Yellow cushion cut diamonds can also be an excellent choice for those seeking something unique and luxurious, as the cushion cut tends to enhance the diamond’s natural hue.

What is the best size for a cushion cut diamond?

When it comes to size, the best size for a cushion cut diamond depends on your budget and personal preference. A 2 carat cushion cut diamond ring on hand offers a substantial and noticeable size that balances beauty and practicality. For those seeking a more significant statement piece, a 4ct cushion cut diamond ring or even an 8 ct cushion cut diamond can create a truly breathtaking effect.

It’s also important to consider the elongated cushion cut ratio if you’re interested in a rectangular cushion cut. The elongated shape can make the diamond appear larger than its actual carat weight, providing a more substantial visual impact without the cost of a higher carat stone.

Clarity is a critical factor when choosing a cushion brilliant cut diamond. Due to the cut’s larger facets, inclusions can be more visible than in other diamond shapes. For this reason, a clarity grade of VS2 or higher is generally recommended for cushion cut stones. In some cases, particularly with larger diamonds like a 3 carat elongated cushion cut, a clarity grade of VS1 or higher may be preferable to ensure that any inclusions are not visible to the naked eye.

How much does a cushion brilliant cut diamond cost?

The cost of a cushion brilliant cut diamond can vary widely based on factors such as carat weight, clarity, color, and cut quality. For example, a 2 ct cushion diamond ring can range from $8,000 to $20,000, depending on these factors. Larger stones, such as a 4 carat cushion cut diamond ring, can cost significantly more, often exceeding $50,000, especially for premium quality stones.

It’s also worth considering the price per carat for cushion cuts versus other shapes. While cushion cuts are generally less expensive per carat than round diamonds, they can be more costly than other fancy shapes, depending on the specific diamond’s characteristics.

Do carats make a difference?

Carat weight significantly impacts both the price and appearance of a diamond. A 2 carat cushion diamond offers a noticeable size that balances beauty and practicality, making it an excellent choice for those looking for something substantial without being overly extravagant. However, for those seeking a true showstopper, a 3 carat elongated cushion cut diamond provides a larger surface area that enhances the diamond’s visual presence, often giving the impression of an even larger stone.

When considering carat weight, it’s also essential to think about the setting. A 4 ct cushion cut diamond ring can be beautifully accentuated with a halo setting, which adds a circle of smaller diamonds around the center stone, enhancing its size and brilliance. Alternatively, a 10 carat cushion cut diamond ring may require a more understated setting to let the diamond’s size speak for itself.

Best engagement ring setting designs for cushion cut diamonds

The setting design is crucial in showcasing the beauty of a cushion cut diamond. Some of the most popular cushion ring setting designs include the halo, solitaire, and three-stone settings. The halo setting, which surrounds the cushion cut stone with smaller diamonds, can make the center diamond appear larger and more brilliant, creating a dazzling effect.

For those who prefer a more minimalist approach, a solitaire cushion cut setting allows the diamond to be the star of the show. This design highlights the diamond’s shape and brilliance without distraction. Another elegant option is the three-stone setting, where two smaller diamonds flank the center cushion cut stone, symbolizing the past, present, and future of your relationship.

How much does a cushion cut diamond cost?

The cost of a cushion cut diamond is influenced by several factors, including carat weight, clarity, color, and cut quality. For instance, a 1ct cushion cut diamond ring can start at around $4,000, while larger stones like an 8 ct cushion cut diamond can reach into the hundreds of thousands of dollars.

When determining how much to spend on a cushion cut diamond, it’s essential to balance quality with budget. While it may be tempting to opt for a larger stone with a lower clarity or color grade, remember that the cushion cut’s larger facets can make inclusions and color more visible. Therefore, investing in a higher quality stone can ensure that your diamond remains stunning for years to come.
